Okay the light tester was interesting, it showed 12V supplied to all leads when the key is on or engine running but one can see that the bottom pin supplies 12 V and then the top pin is energized by the continuity through the coil. The function is obtained by the ground being closed to the top pin..When I ground the top pin the magnet energizes and at low RPM the engine dies, no click or rough idle, just dies. At higher idle it does not die or click but runs..no change in engine sound or speed. I can feel a magnetic effect at the very center of the coil with a screwdriver on connecting the top pin to ground..a VERY weak pull and there is no spark when the top pin is grounded. About like a speaker wire, very low amps. Anyway its normal to have 12V showing here continuously and the coil is activated by grounding through the ECU at the specified RPM. Pretty sure this unit is not functional, and yes doing this triggered an error lite, The ASR light came on and then it reset after one restart.

An added note is that Ive got upgraded wiring and ASR throttle unit, but the lower wiring harness has not been replaced. Its got flakey insulation..And this harness seems to include the cam position sensor and or perhaps an oxygen sensor lead..Ive got the harness but not yet installed it because of bad weather and all the under-car work needed..
